首先提供下NGUI工具接口
/// /// 创建Panel/// /// 父对象/// 名称/// 坐标/// Panel游戏对象public static GameObject createPanel(GameObject parent, string panelName, Vector3 pos){if (parent &＃61;&＃61; null) return null;int depth &＃61; UIPanel.nextUnusedDepth;UIPanel panel &＃61; NGUITools.AddChild(parent);panel.depth &＃61; depth;panel.gameObject.name &＃61; panelName;panel.transform.localPosition &＃61; pos;panel.gameObject.layer &＃61; parent.layer;return panel.gameObject;}/// /// 创建可拖拽的裁剪区/// /// 要被裁剪的Panel/// 裁剪区区域和大小/// 拖拉方向/// 锚点/// 裁剪力度/// UIScrollView对象public static UIScrollView createClipAndDrag(GameObject dragPanel, Vector4 DragCenterAndRange, UIScrollView.Movement moveDiract,UIWidget.Pivot piovt, Vector2 clipSoftness){UIPanel panel &＃61; dragPanel.GetComponent();panel.clipping &＃61; UIDrawCall.Clipping.SoftClip; //裁剪方式//panel.baseClipRegion &＃61; DragCenterAndRange; //裁剪区区域和大小//panel.clipSoftness &＃61; clipSoftness; //裁剪力度//UIScrollView scrollPanel &＃61; dragPanel.AddComponent();scrollPanel.movement &＃61; moveDiract; //拖拉方向//scrollPanel.contentPivot &＃61; piovt; //锚点//scrollPanel.disableDragIfFits &＃61; true;return scrollPanel;}
然后改造一下NGUI的UIScrollView.cs脚本&＃xff0c;添加onDrag托管&＃xff0c;并添加到Drag()中调用
public OnDragNotification onDrag;/// /// Drag the object along the plane./// public void Drag (){if (UICamera.currentScheme &＃61;&＃61; UICamera.ControlScheme.Controller) return;if (enabled && NGUITools.GetActive(gameObject) && mShouldMove){if (mDragID &＃61;&＃61; -10) mDragID &＃61; UICamera.currentTouchID;UICamera.currentTouch.clickNotification &＃61; UICamera.ClickNotification.BasedOnDelta;// Prevents the drag "jump". Contributed by &＃39;mixd&＃39; from the Tasharen forums.if (smoothDragStart && !mDragStarted){mDragStarted &＃61; true;mDragStartOffset &＃61; UICamera.currentTouch.totalDelta;if (onDragStarted !&＃61; null) onDragStarted();}Ray ray &＃61; smoothDragStart ?UICamera.currentCamera.ScreenPointToRay(UICamera.currentTouch.pos - mDragStartOffset) :UICamera.currentCamera.ScreenPointToRay(UICamera.currentTouch.pos);float dist &＃61; 0f;if (mPlane.Raycast(ray, out dist)){Vector3 currentPos &＃61; ray.GetPoint(dist);Vector3 offset &＃61; currentPos - mLastPos;mLastPos &＃61; currentPos;if (offset.x !&＃61; 0f || offset.y !&＃61; 0f || offset.z !&＃61; 0f){offset &＃61; mTrans.InverseTransformDirection(offset);if (movement &＃61;&＃61; Movement.Horizontal){offset.y &＃61; 0f;offset.z &＃61; 0f;}else if (movement &＃61;&＃61; Movement.Vertical){offset.x &＃61; 0f;offset.z &＃61; 0f;}else if (movement &＃61;&＃61; Movement.Unrestricted){offset.z &＃61; 0f;}else{offset.Scale((Vector3)customMovement);}offset &＃61; mTrans.TransformDirection(offset);}// Adjust the momentumif (dragEffect &＃61;&＃61; DragEffect.None) mMomentum &＃61; Vector3.zero;else mMomentum &＃61; Vector3.Lerp(mMomentum, mMomentum &＃43; offset * (0.01f * momentumAmount), 0.67f);// Move the scroll viewif (!iOSDragEmulation || dragEffect !&＃61; DragEffect.MomentumAndSpring){MoveAbsolute(offset);}else{Vector3 constraint &＃61; mPanel.CalculateConstrainOffset(bounds.min, bounds.max);if (constraint.magnitude > 1f){MoveAbsolute(offset * 0.5f);mMomentum *&＃61; 0.5f;}else{MoveAbsolute(offset);}}// We want to constrain the UI to be within boundsif (restrictWithinPanel &&mPanel.clipping !&＃61; UIDrawCall.Clipping.None &&dragEffect !&＃61; DragEffect.MomentumAndSpring){RestrictWithinBounds(true, canMoveHorizontally, canMoveVertically);}if (null !&＃61; onDrag)onDrag();}}}
好了&＃xff0c;创建列表
private GameObject m_dragPanel;private UIScrollView m_scrollView;/// /// 创建列表/// private void createDragList(){m_dragPanel &＃61; NGUIComponentFactory.createPanel(m_gamePanel, "dragPanel", Vector3.zero);m_scrollView &＃61; NGUIComponentFactory.createClipAndDrag(m_dragPanel, new Vector4(0, 29.5f, 500, 360),UIScrollView.Movement.Vertical, UIWidget.Pivot.Top, Vector2.one);m_scrollView.onDragFinished &＃61; onPanelDragFinished;m_scrollView.onDrag &＃61; onPanelOnDrag;//创建列表项//}
然后定义托管回掉函数
private UILabel m_loadMoreTips;private int m_curDisplayNum;private void onPanelDragFinished(){if (null !&＃61; m_loadMoreTips){//创建更多项目//}}private void onPanelOnDrag(){if (null &＃61;&＃61; m_dragPanel || null &＃61;&＃61; m_scrollView) return;Vector3 constraint &＃61; m_dragPanel.GetComponent().CalculateConstrainOffset(m_scrollView.bounds.min, m_scrollView.bounds.max);if (null &＃61;&＃61; m_loadMoreTips && constraint.y <0){m_loadMoreTips &＃61; NGUIComponentFactory.createLabel(m_dragPanel, "tipsLoadMore", ResourceManager.instance.myFont,new Vector3(0, 250f - 102f * m_curDisplayNum - 85f, 0), 30);m_loadMoreTips.overflowMethod &＃61; UILabel.Overflow.ResizeFreely;m_loadMoreTips.text &＃61; "加载更多";}}
创建Label的接口如下
/// /// 创建Label/// /// 父对象/// 名称/// 字体/// 坐标/// 大小/// UILabel对象public static UILabel createLabel(GameObject parent, string labelName, UIFont font, Vector3 pos, int fontSize){UILabel lbl &＃61; NGUITools.AddWidget(parent);lbl.gameObject.name &＃61; labelName;lbl.bitmapFont &＃61; font;lbl.fontSize &＃61; fontSize;Transform transform &＃61; lbl.gameObject.transform;transform.localPosition &＃61; pos;return lbl;}
好了&＃xff0c;其他逻辑请自己脑补吧
